The layout engine should have a UI creation module

Although it is possible to create a fully functional UI with the layout engine, it's use has a steep learning curve and is not exactly intuitive to use. There are many standard UI items most apps use (standard UI library items such as panels, check boxes, lists, etc). Creating each one of those is a lot of work and fiddly to handle and maintain.

Rive should have a standard UI library creation module which automates a lot of the standard universally used items.
